Description
    BACKGROUND
  • [0001]
    1. Technical Field
  • [0002]
    The present disclosure relates to gaskets and, more particularly, to composite gaskets for use in conjunction with stapling devices, for reducing occurrences of leaking, bleeding and/or stricture when anastomosing various body structures.
  • [0003]
    2. Background of Related Art
  • [0004]
    Staples have traditionally been used to replace suturing when joining or anastomosing various body structures such as, for example, the bowel or bronchus. The surgical stapling devices employed to apply these staples are generally designed to simultaneously cut and seal an extended segment of tissue in a patient, thus vastly reducing the time and risks of such procedures.
  • [0005]
    Linear or annular surgical stapling devices are employed by surgeons to sequentially or simultaneously apply one or more linear rows of surgical fasteners, e.g., staples or two-part fasteners, to body tissue for the purpose of joining segments of body tissue together and/or for the creation of anastomoses. Linear surgical stapling devices generally include a pair of jaws or finger-like structures between which body tissue to be joined is placed. When the surgical stapling device is actuated and/or “fired”, firing bars move longitudinally and contact staple drive members in one of the jaws, and surgical staples are pushed through the body tissue and into/against an anvil in the opposite jaw thereby crimping the staples closed. A knife blade may be provided to cut between the rows/lines of staples. Examples of such surgical stapling devices are described in U.S. Pat. Nos. 4,354,628, 5,014,899 and 5,040,715, the entirety of each of which is incorporated herein by reference.
  • [0006]
    In addition to the use of surgical staples, biological tissue adhesives have been developed for tissue repair and the creation of anastomoses. Generally, biological adhesives bond separated tissues together to aid in the healing process and to enhance tissue strength. Such adhesives may be used instead of suturing and stapling, for example, in surgical procedures for the repair of tissue or the creation of anastomoses.
  • [0007]
    Generally, following the formation of the anastomosis, a separate instrument or device is used to apply biological sealants to the outer surface of the anastomosis. Typically, in a separate step, the biological sealants are applied to the outer surface of the anastomosis by spraying, brushing, swabbing, any combinations thereof, or any other method contemplated by those skilled in the art. The biological sealants act to reduce and/or stop the incidents of leakage from the anastomosis.
  • [0008]
    The application of a suitable biocompatible adhesive offers many advantages to the patient and the surgeon alike, such as, for example, the possible reduction in the number of staples used, immediate sealing of the tissue being treated, a strengthening of the anastomosis, and a reduction in the occurrence of bleeding from the blood vessels, leakage through the tissue joint, and stricture. Moreover, use of biocompatible adhesives tends to minimize foreign body reaction and scarring.
  • [0009]
    Annular surgical stapling devices generally include an annular staple cartridge assembly including a plurality of annular rows of staples, typically two, an anvil assembly operatively associated with the annular cartridge assembly, and an annular blade disposed internal of the rows of staples. Examples of such annular surgical stapling devices are described in U.S. Pat. Nos. 5,799,857 and 5,915,616 to Robertson et al., the entirety of each of which is incorporated herein by reference.
  • [0010]
    In general, an end-to-end anastomosis stapler typically places an array of staples into the approximated sections of a patient's bowels or other tubular organs. The resulting anastomosis contains an inverted section of bowel which contains numerous “B” shaped staples to maintain a secure connection between the approximated sections of bowel.
  • [0011]
    For most procedures, the use of bare staples, with the staples in direct contact with the patient's tissue, is generally acceptable. The integrity of the tissue will normally serve to prevent the staples from tearing out of the tissue and compromising the sealing before healing has occurred. However, in some surgical operations, surgical supports, e.g., meshes, are employed by surgeons in combination with linear stapling devices to bridge, repair and/or reinforce tissue defects within a patient, especially those occurring in the abdominal wall, chest wall, diaphragm, and other musculo-aponeurotic areas of the body. Examples of suitable surgical supports are disclosed in U.S. Pat. Nos. 3,054,406, 3,124,136, 4,347,847, 4,655,221, 4,838,884 and 5,002,551, the entirety of each of which is incorporated herein by reference.
  • [0012]
    When the staples are applied in surgical procedures utilizing surgical supports (i.e., reinforcing material), the legs of the staple typically pass from the cartridge jaw through a layer of the surgical support, and through the patient's tissue before encountering the anvil jaw. In an alternative procedure, the legs of the staple typically pass from the cartridge jaw through a first layer of the surgical support, then through the patient's tissue, and finally through a second layer of the surgical support before encountering the anvil jaw. With the staples in place, the stapled tissue is clamped between the layers of the surgical support.
  • [0013]
    While the surgical supports described above are used in conjunction with linear surgical stapling devices, the need exists for annular support structures for use in conjunction with annular or circular surgical stapling devices, for example, an end-to-end anastomosis stapler such as a Model “EEA™” instrument available from United States Surgical, a Division of Tyco Health-Care Group, LP, Norwalk, Conn. and disclosed in U.S. Pat. No. 5,392,979 to Green et al.
  • [0014]
    One possible side effect of any end-to-end bowel anastomosis is its tendency to undergo stenosis over time, which can decrease the diameter of the lumen over time. Accordingly, the need exists for an annular surgical structure which operates in conjunction with any end-to-end, annular, or circular anastomosis or stapling device and assists in keeping open the lumen of the anastomosed bowel or other tubular organ over time. There is also a need for a gasket, which would function to seal the anastomosed bowel or other body organ against leakage from between the tissue sections being joined.
  • [0015]
    A need also exists for an annular support structure which operates in conjunction with any end-to-end, annular or circular stapling device to reduce the trauma suffered by the patient, reduce the instances of leakage, reduce the instances of bleeding, and create a relatively strong bond between adjacent body tissues.

In another embodiment, the distance between outer ring 106 and inner ring 102 is substantially equal to a width of a tissue contacting surface 24 (see FIG. 1) of staple cartridge assembly 22.
  • [0053]
    As seen in FIG. 3, circular anastomosis structure 100 includes at least two concentric rings. Where a three ring structure is utilized, as shown in FIGS. 2 and 3, structure 100 includes an inner ring 102, a middle ring 104 and an outer ring 106. Where a two ring structure is utilized (not shown), structure 100 includes a middle ring 104 and an outer ring 106. In this embodiment, inner ring 102 is missing and/or is otherwise optional.
  • [0054]
    It is contemplated that inner ring 102 may, in some embodiments, be made from non-absorbable materials including, but not limited to, both synthetic and natural materials, including polyolefins such as polypropylenes, nylon, and silk. Inner ring 102 may also be made of absorbable materials, including homopolymers, copolymers or blends obtained from one or more monomers selected from the group consisting of glycolide, glycolic acid, lactide, lactic acid, p-dioxanone, e-caprolactone and trimethylene carbonate. In some embodiments, inner ring 102 may be a composite of both non-absorbable and absorbable materials.
  • [0055]
    As seen in FIG. 3, in one embodiment the inner ring may 102 have one or more gaps 114 formed therein and/or therealong to help facilitate passage of inner ring 108 out of the patients' body and to help facilitate introduction of shaft 28 of anvil assembly 30 into aperture 108.
  • [0056]
    It is contemplated that middle ring 104 of structure 100 may be fabricated from or include a surgical grade, biocompatible, non-absorbable (i.e., permanent) or absorbable (i.e., non-permanent) mesh or material desirably impregnated with an adhesive, sealant and/or other medicament. As used herein, “mesh” includes woven, knitted and braided materials. In addition, non-woven materials such as felts may be used. For example, middle ring 104 may be fabricated from “TEFLON”, which is a registered trademark owned by DuPont de Nemours & Co. It is further contemplated that middle ring 104 may be fabricated from a biocompatible polymeric foam, felt, polytetrafluoroethylene (ePTFE), gelatin, fabric or the like, or any other biocompatible material.
  • [0057]
    Non-absorbable materials used for middle ring 104 include, but are not limited to, those that are fabricated from such polymers as polybutester, polyetherester, polyethylene, polypropylene, nylon, polyethylene terephthalate, polytetrafluoroethylene, polyvinylidene fluoride, and the like. Further non-absorbable materials which may be utilized include, but are not limited to, stainless steel, titanium and the like.
  • [0058]
    Bio-absorbable materials used for middle ring 104 of structure 100 include, but are not limited to, those fabricated from homopolymers, copolymers or blends obtained from one or more monomers selected from the group consisting of glycolide, glycolic acid, lactide, lactic acid, p-dioxanone, e-caprolactone and trimethylene carbonate. Other bio-absorbable materials include, but are not limited to, polyglycolic acid (PGA) and polylactic acid (PLA). In one embodiment, middle ring 104 may be fabricated from bio-absorbable felt, ePTFE, gelatin or any other bio-absorbable materials. In one particularly useful embodiment, polyglycolic acid (PGA) yarns may be used as the middle ring 104 of the circular anastomosis structure of the present disclosure. Suitable yarns include those sold in a mesh form as DEXON™ mesh by United States Surgical, a Division of Tyco Health-Care Group, LP, Norwalk, Conn.
  • [0059]
    In one particularly useful embodiment, as seen in FIG. 2A, middle ring 104 may be made from a composite material made from a majority 110 of an absorbable yarn with a minority 112 of non-absorbable yarn, such as silk, cotton, nylon, polypropylene, polyester, polyethylene terephtialate, and the like. In some cases, it may be advantageous to include a minor portion of a non-absorbable yarn to increase tissue growth by enhancing tissue reactivity. While materials such as silk, cotton and nylon are classified by the FDA as non-absorbable materials, they will eventually break-down in the body, at a much slower rate than absorbable materials.
  • [0060]
    As with inner ring 102, in some embodiments middle ring 104 may be a composite of both non-absorbable and absorbable materials.
  • [0061]
    Outer ring 106 may similarly be made of non-absorbable or absorbable materials described above for use in forming middle ring 104 or inner ring 102. In some embodiments, outer ring 106 may also be made from a composite of absorbable materials combining a knitted mesh such as DEXON™ mesh with an absorbable synthetic wax or synthetic sealant. For example, this absorbable material can be made from short-chain polymer(s) such as glycolide, lactide, trimethylene carbonate, dioxanone or the like, and any combinations thereof.
  • [0062]
    In a further embodiment, the structure has a middle ring and an inner ring and incorporates at least two different materials. The inner ring is formed from a non-bioabsorbable material, whereas the middle ring is formed from bio-absorbable materials and is preferably a compressible material arranged to be compressed between adjacent tissue sections so as to form a seal. The inner ring is desirably arranged so as to be at least partially removed by the circular knife of the stapling device and/or passed from the body.
  • [0063]
    As noted above, in some embodiments a minor portion of a non-absorbable material may also be incorporated into inner ring 102, outer ring 106, or both.
  • [0064]
    In yet another embodiment, as seen in FIGS. 4 and 5, middle ring 104 can be made from a sandwich of composite materials including an upper layer 104 a and a lower layer 104 b. Desirably, layers 104 a, 104 b may be a knitted mesh made from both absorbable and non-absorbable yarns and include a sealant as a middle layer to secure layers 104 a, 104 b to one another. Sealants which may be utilized to adhere the upper and lower layers 104 a, 104 b of the middle ring are known to those skilled in the art and include, but are not limited to, hydrogels, fibrin-based sealants, thrombin-based sealants, collagen-based sealants, and synthetic polymer sealants including those based on polyalkylene oxides such as polyethylene glycol, polydioxanones, polylactides, polyglycolides, polycaprolactones. In one particularly useful embodiment, the sealant utilized to adhere the upper and lower layers 104 a, 104 b of middle ring 104 is an absorbable sealant which swells after contact with water, e.g., a hydrogel, which is analogous to a “foam in place” sealant.
  • [0065]
    In yet another embodiment, the multi-layer composite mesh utilized to form the middle ring 104 may be pre-impregnated (i.e., coated) with the swelling absorbable sealant.
  • [0066]
    In one embodiment, middle ring 104 of structure 100 may be fabricated from a bio-absorbable material which is desirably impregnated with an adhesive, sealant, and/or other medicament (i.e., wound treatment material). Accordingly, in use, the sealant component of structure 100 functions to retard any bleeding which may occur from the tissue, the adhesive component of structure 100 functions to help secure the approximated tissue together, and the bio-absorbability of structure 100 allows for at least a portion of structure 100 to be absorbed into the body after a predetermined amount of time. For example, structure 100 may remain in place in the body for approximately 2-3 weeks in order for the anastomosis to sufficiently heal prior to structure 100 being absorbed into the body.
  • [0067]
    Where utilized, the adhesive should be a biocompatible adhesive including, but not limited to, adhesives which cure upon tissue contact, which cure upon exposure to ultraviolet (UV) light, which are two-part systems kept isolated from one another and cure upon coming into contact with one another, which are pressure sensitive, which are any combinations thereof, or any other known suitable adhesive. In one embodiment, it is contemplated that an adhesive having a cure time of from about 10 to about 15 seconds may be used. In another embodiment, it is contemplated that an adhesive having a cure time of about 30 seconds may be used.
  • [0068]
    It is envisioned that middle ring 104 of structure 100 may be impregnated with a pre-cured adhesive or sealant. The pre-cured sealant or adhesive will react with the moisture and/or heat of the body tissue to thereby activate the sealing and/or adhesive properties of the sealant or adhesive. Thus, in one embodiment the pre-cured sealant or adhesive may be a hydrogel or the like.
  • [0069]
    It is envisioned that the adhesive may be utilized alone or combined with one or more other wound treatment materials. Other surgically biocompatible wound treatment materials which may be employed in or applied by surgical instruments, especially surgical staplers utilized to repair tissue and create anastomosis with the anastomosis composite structure herein, include adhesives whose function is to attach or hold organs, tissues or structures; sealants to prevent fluid leakage; hemostats to halt or prevent bleeding; and medicaments.

The medicament may include one or more medically and/or surgically useful substances such as drugs, enzymes, growth factors, peptides, proteins, dyes, diagnostic agents or hemostatic agents, or any other pharmaceutical used in the prevention of stenosis.
  • [0079]
    In one embodiment, it is contemplated that middle ring 104 of structure 100 may be impregnated with a first component of a two-part adhesive and that the staples, retained in staple receiving slots 36 of staple cartridge assembly 22, may be coated with a second component (e.g., a reactant) of the two-part adhesive. In this manner, the first component of the adhesive is activated when the staples penetrate and capture middle ring 104 of structure 100 during the firing sequence of surgical stapling device 10, and the two components of the adhesive contact one another.
  • [0080]
    As seen in FIG. 3, structure 100 may include a single layered middle ring 104 including a homogeneous array of bio-absorbable or non-absorbable materials or a heterogeneous array or bio-absorbable and/or non-absorbable materials.
  • [0081]
    As seen in FIGS. 4 and 5 and as discussed above, structure 100 may include at least a dual layered middle ring 104 as indicated by first layer, film or wafer 104 a and second layer, film or wafer 104 b. In this embodiment, each layer 104 a, 104 b may include a homogeneous or heterogeneous array of bio-absorbable and/or non-absorbable materials. It is envisioned that each layer 104 a, 104 b may be separated from one another, as seen in FIG. 5, prior to the surgical procedure.
  • [0082]
    As will be described in greater detail below, first layer 104 a of structure 100 may be placed against a surface of a first tissue to be anastomosed, in juxtaposition to a second tissue to be anastomosed, and second layer 104 b of structure 100 may be placed against a surface of the second tissue to be anastomosed, in juxtaposition to the first tissue to be anastomosed. In this manner, as the first and second tissues are brought into contact with one another, first and second layers 104 a, 104 b of structure 100 are brought into contact with one another and allowed to mix and/or react. For example, first layer 104 a of structure 100 may include a first component of a two-part adhesive or sealant while second layer 104 b of structure 100 may include a second component of the two-part adhesive or sealant. Accordingly, in use, when first layer 104 a and second layer 104 b come into contact with one another, the first and second components of the two-part adhesive or sealant will also come into contact and mix thereby forming the adhesive or sealant.
  • [0083]
    First and second layers 104 a and 104 b may be fabricated as bio-absorbable film-like membranes which activate upon contact with one another and/or contact with a fluid (e.g., water, saline, blood, an activating fluid, etc.). It is envisioned that a break-away or tear-away divider or barrier (not shown) may be positioned between first and second layers 104 a, 104 b in order to prevent accidental and/or premature contact between first and second layers 104 a and 104 b. It is further envisioned that each first and second layer 104 a and 104 b may include a liner (not shown) removably disposed on at least one of a top or bottom surface thereof. In any of these embodiments, prior to contact of first and second layers 104 a and 104 b with one another, the divider and/or liners must be removed in order for activation of the adhesive to occur.
  • [0084]
    It is further envisioned that middle ring 104 of structure 100 may be impregnated with a pressure sensitive adhesive which is activated when the adjacent layers of tissue are approximated. Suitable pressure sensitive adhesives are known to those skilled in the art and include, for example, acrylate polymers, methacrylate polymers. In some embodiments, the pressure sensitive adhesive may be an alkyl methacrylate including, but not limited to, alkyl methacrylates containing 1 to about 10 carbon atoms in the alkyl group. Representative examples of suitable alkyl methacrylates include methyl methacrylate, n-butyl methacrylate, n-pentyl methacrylate, n-hexyl methacrylate, isoheptyl methacrylate, cyclohexyl methacrylate, n-nonyl methacrylate, n-decyl methacrylate, isohexyl methacrylate, 2-ethyloctyl methacrylate, isooctyl methacrylate, isobornyl methacrylate, 2-ethylhexyl methacrylate, and mixtures and combinations of the foregoing. Typically, the alkyl methacrylate may be isooctyl methacrylate, butyl methacrylate, 2-ethylhexyl methacrylate, cyclohexyl methacrylate, isobornyl methacrylate, and/or methyl methacrylate.
  • [0085]
    In some embodiments, the pressure sensitive adhesive may be a copolymer including an alkyl methacrylate described above copolymerized with one or more methacrylate monomers having at least one functional group selected from the grouping consisting of carboxylic acid, carboxylic acid ester, hydroxyl, anydride, epoxy, thiol, isocyanate, sulfonamide, urea, carbamate, carboxamide, amine, ammonium, oxy, oxo, nitro, nitrogen, sulfur, phosphate, phosponate, cyano, combinations of these, and the like. Representative examples of specific materials that can be used singly or in combination as the methacrylate monomer having at least one functional group include methacrylic acid, maleic acid, vinyl acetate, a hydroxyalkyl methacrylate containing about 2 to about 4 carbon atoms in the hydroxyalkyl group, methacrylamide, an alkyl substituted methacrylamide having 1 to about 8 carbon atoms in the alkyl group, diacetone methacrylamide, a dialkyl methacrylamide independently having 1 or 2 carbon atoms in each alkyl group, N-vinyl-N-methyl acetamide, N-vinyl lactams, N-vinyl valerolactam, N-vinyl caprolactam, N-vinyl-2-pyrrolidone, glycidyl methacrylate, alkoxy methacrylate containing 1 to 4 carbon atoms in the alkoxy group, 2-ethoxyethyl methacrylate, 2,2-ethoxyethoxyethyl methacrylate, furfuryl methacrylate, tetrahydrofurfuryl methacrylate, propylene glycol monomethacrylate, polyethylene glycol methacrylate, polyethylene glycol methyl ether methacrylate, polyethylene oxide methyl ether methacrylate, di(lower)alkylaminopropyl methacrylamide (wherein lower means the alkyl moiety has 1 to 4 carbon atoms), methacrylonitrile, combinations of these, and the like. Typically, the copolymerizable monomer having at least one functional group include may be hydroxyethyl acrylate, hydroxyethyl methacrylate, acrylamide, glyceryl acrylate, N,N-dimethyl acrylamide, 2-ethoxyethyl acrylate, 2,2-ethoxyethoxyethyl acrylate, tetrahydrofurfuryl acrylate, vinyl acetate, and/or acrylic acid. Any of the aforementioned alkyl groups may be linear, branched or cyclic.
  • [0086]
    As seen in FIG. 6, in use structure 100 may be placed such that aperture 108 receives shaft 28 of anvil assembly 30 therethrough and is at least substantially axially aligned with staple receiving slots 36 (see FIG. 1) of cartridge assembly 22.
  • [0087]
    Turning now to FIGS. 7 and 8, there is illustrated the use of surgical stapling device 10 and detachable anvil assembly 30 in an anastomosis procedure to effect joining of intestinal sections 66 and 68. The anastomosis procedure is typically performed using minimally invasive surgical techniques including laparoscopic means and instrumentation. At the point in the procedure shown in FIG. 7, a diseased intestinal section has been previously removed, anvil assembly 30 has been applied to the operative site either through a surgical incision or transanally and positioned within intestinal section 68, and tubular body portion 20 of surgical stapling device 10 has been inserted transanally into intestinal section 66. Intestinal sections 66 and 68 are also shown temporarily secured about their respective components (e.g., shaft 28 of anvil assembly 30, and the distal end of tubular body portion 20) by conventional means such as a purse string suture “P” (see FIG. 8).
  • [0088]
    According to one method, as seen in FIG. 8, if desired or if the surgical procedure requires, circular anastomosis structure 100 may be placed onto shaft 28 of anvil assembly 30 prior to the coupling of anvil assembly 30 to the distal end of tubular body portion 20. Following positioning of structure 100 onto shaft 28 of anvil assembly 30, the surgeon maneuvers anvil assembly 30 until the proximal end of shaft 28 is inserted into the distal end of tubular body portion 20 of surgical stapling device 10, wherein the mounting structure (not shown) within the distal end of tubular body portion 20 engages shaft 28 to effect the mounting.
  • [0089]
    Thereafter, anvil assembly 30 and tubular body portion 20 are approximated to approximate intestinal sections 66, 68 and capture circular anastomosis structure 100 therebetween. Surgical stapling device 10 is then fired thereby stapling intestinal sections 66, 68 to one another and cutting the portion of tissue and structure 100 disposed radially inward of the knife, to complete the anastomosis. Structure 100 may then release the adhesive impregnated therein to thereby adhere intestinal sections 66 and 68 to one another.
  • [0090]
    In the event that a structure 100 having a first and second layer 104 a and 104 b, each including one part of a two-part adhesive composition, is used, it is envisioned that first and second layers 104 a and 104 b are maintained separated and/or isolated from one another until approximation and firing of the surgical stapling device is to occur. Accordingly, in use, one of first and second layers 104 a, 104 b may be placed on shaft 28 of anvil assembly 30, against the surface of intestinal section 68, while the other of first and second layers 104 a, 104 b is placed against the surface of intestinal section 66. It is envisioned that pins (not shown) may extend distally from the distal end of tubular body portion 20 and penetrate through intestinal section 66. In this manner, the other of first and second layers 104 a, 104 b may be pinned onto the pins extending through intestinal section 66.
  • [0091]
    Alternatively, if a structure 100, having a first and second layer 104 a and 104 b, each including one part of a two-part adhesive composition, is used, it is envisioned that that each layer 104 a, 104 b may be provided with a tear-away or removable liner for maintaining first and second layers 104 a, 104 b separated and/or isolated from one another. Accordingly, both first and second layers 104 a, 104 b may be placed on shaft 28 of anvil assembly 30.
  • [0092]
    If a structure 100, having a first and second layer 104 a, 104 b each including one part of a two-part adhesive composition, is used, the adhesive composition may be activated upon first and second layers 104 a, 104 b coming into contact with one another.
  • [0093]
    From the foregoing, it will be appreciated that the circular anastomosis structures of the present disclosure function to strengthen the anastomosis and reduce the occurrence of bleeding, leaking and stricture. It is also to be appreciated that the circular anastomosis structures of the present disclosure may be utilized in a number of other applications and is not limited solely to bowel or bronchus anastomosis.
  • [0094]
    Each circular anastomosis structure described above is constructed to enhance the formation of an anastomosis at the target surgical site. In some embodiments, the circular anastomosis structure may also be used to deliver an adhesive to the surgical site. The amount of adhesive to be delivered is site specific. Accordingly, different sized (e.g., different thickness or different volume) circular anastomosis structures are contemplated for retaining a different volume or quantity of adhesive therein. In this manner, depending on the particular need and the particular surgical procedure, the surgeon may select a circular anastomosis structure containing the needed and/or desired volume or quantity of adhesive therein.
  • [0095]
    While several particular forms of the circular anastomosis structures have been illustrated and described, it will also be apparent that various modifications can be made without departing from the spirit and scope of the present disclosure. For example, it is envisioned and within the scope of the present disclosure for an ultraviolet light activated adhesive to be used in connection with any of the circular anastomosis structures described above. In use, either prior to or following firing of surgical stapling device 10, the circular anastomosis structure is irradiated with UV light to thereby activate the adhesive.
  • [0096]
    It is further contemplated that each of the circular anastomosis structures described herein may be used with an annular surgical anastomosing device, not including any staples for securing tissue together, which is capable of approximating, adhering and cutting tissue.
  • [0097]
    Thus, it should be understood that various changes in form, detail and application of the circular anastomosis structures of the present disclosure may be made without departing from the spirit and scope of the present disclosure.
